An AP AC joint projection with a kyphotic patient will require a _____ angulation of the CR, aligned perpendicular to the _____.

Question

Quizplus · Accepted Answer

A kyphotic patient will have a more rounded upper thoracic spine, requiring a cephalic angulation of the CR to align it perpendicular to the scapular body. Option A and D are incorrect because a caudal angulation of the CR would cause the scapula to overlap the humeral head, which is not desired in an AP AC joint projection. Option C is also incorrect because it focuses on the upper one-third of the humerus rather than the AC joint.
